- Introduce new NET_CompareBaseAdrMask for easy comparison of ip address ranges

- Overhaul of the new banning functions:
  * basic check for redundant bans/exceptions
  * introduction of sv_banFile to make it possible to configure the file where to read bans and exceptions from
  * bans can now be deleted by giving address ranges, too.
